Roy:

I have the same problem with my '87.

Don't worry about replacing all the guts though. The solution is simple and
absolutely FREE!!!

All you have to do is wad or fold 3 or 4 pieces of the windshield wiping
paper found next to the gas pump and put them between the nozzle and the
van. This will soak up the overspill and still allow enough left-over dry
space to allow for disposal into the trash recepticle (so you won't have to
worry about smeeling like gas).

You may end-up spending an extra .25 or .50 cents on gas per year, but it
sure beats ripping the heck out of your baby and crossing your fingers that
you put everything back the right way and that it will work right, even if
you do.

Hope this helps.
